We explore graphs of high cop number. We give new lower bounds for cop number of graphs of high girth. We also present a new class of undirected graphs with cop number $(1-o(1)) \sqrt{n/2}$ and a class of directed graphs with cop number $(1-o(1))...

Please bring your favourite (math) problems. Anyone with a problem to share will be given about 5 minutes to present it. We will also choose most of the speakers for the rest of the semester.

In this talk we introduce a mathematical model to describe temporal processes like embryonic development and cellular reprogramming. We consider stochastic processes in gene expression space to represent developing populations of cells, and we use...

Solvers for the Boolean satisfiability problem have been increasingly used to solve hard problems from many fields and now routinely solve problems with millions of variables. Combinatorial problems are a natural target, as SAT solvers contain...

Let K be a field, let t : K à K be an automorphism of order 1 or 2. Let F denote the subfield of t-invariant elements in K. Then either K=F or K/F is a quadratic Galois extension. Given a central simple K-algebra A, a t-involution of A is an anti...

These are algebraic surfaces with the Betti numbers of the complex projective plane, and are called $Q$-homology projective planes. We describe recent progress in the study of such surfaces including smooth examples, the fake projective planes. We...

We investigates the globally stabilizing effects of the geometry of the domain and the solution in studying the regularity issue on the three-dimensional incompressible Navier-Stokes and Euler system. We establish the global existence and uniqueness...

The four-week industry fellowships, which are being run in partnership with Cybera, bring together six companies wanting to leverage data science, and 22 newly trained data scientists in Edmonton and Calgary. The companies have presented a challenge...

Consider the Monge-Kantorovich problem of transporting densities $\rho_0$ to $\rho_1$ on $\rr^d$ with a strictly convex cost function. A popular relaxation of the problem is the one-parameter family called the entropic cost problem. The entropic cost...

Speakers: (1) Zheng Hua, University of Hong Kong (2:30-3:30) Title: Noncommutative differential calculus and Calabi-Yau geometry Quivers with potential appear naturally in the study of the deformation theory of objects in 3D Calabi-Yau categories...
